Description
Technical field
The invention belongs to electric vehicle engineering fields.
Background technology
As fossil energy is increasingly in short supply, exhaust pollution caused by fuel-engined vehicle is more serious, Development of EV is vapour
Turner industry walks the inevitable choice of sustainable development path, therefore electric vehicle causes the concern of various circles of society.However, it makes at present
The problem of mainly electric vehicle course continuation mileage of about Development of Electric Vehicles is too short, although government is charged by taking to increase
This exterior measures of stake quantity try to improve this case, but still can't resolve critical issue, it is desired nonetheless to from electric vehicle
Solution is considered in internal factor.For electric vehicle in itself, the vibrational energy in damper is the very considerable energy, but one
As all by people ignore and slattern.If this practicability and high power density and the vibrational energy deposited can be adopted
Collect, generate electricity and store, that is meaningful to the course continuation mileage for extending electric vehicle.
According to retrieval, the regeneration damper for recycling automobile vibrational energy existing at present, such as application No. is
201710223415.9 Chinese patent disclose a kind of automobile vibrational energy and recycle damper, pass through rack-and-pinion, increase
Combination between fast device, one-way clutch and generator reduces the damper dissipation of energy during motor racing, improves
The utilization rate of energy.But this device for mechanical transmission device, speed increaser and generator are laterally disposed, bulky, about
It is the seven to eight times of common damper system, installation is too poor；Tooth root easily occurs during rack pinion simultaneously to fracture, durability
It is not strong.
For another example the Chinese patent of Patent No. 201620804506.2 discloses a kind of shaking for plug-in hybrid-power automobile
Energy retracting device stores electric energy so as to save energy by hydraulic system.This system structure is complex, installation cost
Height, and it is susceptible to the situation of oil leak.
In view of the above circumstances, it is necessary to research and develop a kind of compact, simple in structure, universal durable, of low cost but power generation
Efficient energy regenerative damper.
Invention content
The object of the present invention is to provide a kind of dampers for recycling automobile vibrational energy, it can effectively solve the problem that damper hangs down
The problem of straight movement is converted to generator unidirectional rotary motion.
The purpose of the present invention is achieved through the following technical solutions：A kind of damper for recycling automobile vibrational energy,
Including upper bush, lower sleeve, movement conversion mechanism and generator, the engaging portion between upper bush and lower sleeve is matched for gap
It closes.Upper bush is motor bin to become the hollow barrel structure of internal diameter, the small internal diameter section in top, and small internal diameter section end is equipped with shoulder block and axis hole,
Generator is located in motor bin, and casing tail end is fixed by upper end cover and upper bush, and front end is concordant with shoulder block, and motor shaft is downward

Machine 3, the engaging portion between upper bush 1 and lower sleeve 2 are clearance fit.For upper bush 1 to become the hollow barrel structure of internal diameter, top is small interior
Diameter section is motor bin, and small internal diameter section end is equipped with shoulder block and axis hole, and generator 3 is located in motor bin, and casing tail end passes through upper end
Lid 13 is fixed with upper bush 1, and front end is concordant with shoulder block, and for motor shaft 15 downward and across axis hole, the middle part and end of the axis are equal
Equipped with unilateral bearing 6,15 middle part of motor shaft and the inner ring interference of the unilateral bearing 6 positioned at 1 lower part large diameter section top of upper bush
Cooperation, 4 inner end diameter of the outer ring transmission cylinder interference fit of the unilateral bearing 6,6 outer ring of unilateral bearing and the connection of 15 end of motor shaft
The axis hole of 7 upper end of axis device is fixed, and the lower end of shaft coupling 7 is connect with the upper end of dextrorotation leading screw 11；4 outer diameter of transmission cylinder and the first thrust
The inner ring interference fit of bearing 5, the first thrust bearing 5 by the shaft shoulder of 1 inner wall of upper bush and be fixed on the iron hoop 16 of inner wall into
Row positioning；Second thrust bearing, 10 inner ring is interference fitted with 11 top of dextrorotation leading screw, and outer ring and the internal diameter of transmission cylinder 4 are matched for interference
Merga pass shoulder block positions；The bottom diameter of transmission cylinder 4 is equipped with the left-handed nut with 9 clearance fit of left-handed leading screw of hollow structure
12, left-handed 9 upper end of leading screw is internally provided with the right-handed nut 8 engaged with dextrorotation leading screw 11, the lower end of left-handed leading screw 9 by bolt with
14 inside of bottom end cover is fixed；The lower end of lower sleeve 2 is fixed by bolt and bottom end cover 14.
Described two 6 directions of unilateral bearing are opposite.
The transmission cylinder 4 is formed by connecting by two and half round buss by bolt and nut.
The iron hoop 16 is bonded, and pass through electric welding on 1 inner wall of upper bush with 5 lower section of the first thrust bearing.
The present invention passes through a left-handed right-handed nut 8 of dextrorotation leading screw 11, one of leading screw 9, one and a left-handed nut 12
Use, can realize that the up and down motion by two sleeves is converted to the rotation opposite with 11 both direction of dextrorotation leading screw of transmission cylinder 4
Movement；The characteristics of being freely rotated by unilateral bearing 6, being locked on another direction in one direction and shaft coupling 7
Use, the rotary motion opposite with the both direction of transmission cylinder 4 of dextrorotation leading screw 11 can be converted to the unidirectional rotation of motor shaft 15
Transhipment is dynamic, so as to greatly improve generating efficiency, avoids the various shortcomings of bidirectional rotation power generation, improves the resistance to of generator
The property used.The use of thrust bearing 5,10 reduces axial load and the pressure of unilateral bearing 6 and motor shaft 15 is acted on, and extends
The service life of the present apparatus.
Working process and principle of the invention：When automobile is in flipper turn or traveling is when on uneven road,
The upper bush 1 of affixed damper and lower sleeve 2 have opposite vertical and straight movement up and down with suspension.
When distance reduces between upper bush 1 and lower sleeve 2, the left-handed leading screw 9 being fixed on bottom end cover 14 moves up,
Above damper, the left-handed nut 12 being engaged with counterclockwise rotates, therefore the transmission affixed with left-handed nut 12
Cylinder 4 also rotates counterclockwise；It is also secured to the right-handed nut 8 inside left-handed leading screw 9 to move up, the dextrorotation leading screw being engaged with
11 rotate clockwise；Because there is unilateral bearing 6, the transmission cylinder 4 rotated counterclockwise cannot deliver torque to motor shaft
15, and dextrorotation leading screw 11 can drive motor shaft 15 to rotate toward the clockwise direction, generator 3 starts to generate electricity, and exports electric energy.
When distance increase between upper bush 1 and lower sleeve 2, the left-handed leading screw 9 being fixed on bottom end cover 14 moves down,
Above damper, the left-handed nut 12 being engaged with is rotated clockwise, therefore the transmission affixed with left-handed nut 12
Cylinder 4 also rotates clockwise；It is also secured to the right-handed nut 8 inside left-handed leading screw 9 to move down, the dextrorotation leading screw being engaged with
11 rotate counterclockwise；Because there is unilateral bearing 6, the dextrorotation leading screw 11 rotated counterclockwise cannot deliver torque to motor
Axis 15, and transmission cylinder 4 can drive motor shaft 15 still to rotate with the sun, generator 3 continues to generate electricity, and exports electric energy.
